Triangle Jump (三角跳び Sankaku tobi?) is a move used by Sonic the Hedgehog, Shadow the Hedgehog and Espio the Chameleon. It was first introduced in Sonic Heroes and appeared later in Shadow the Hedgehog. This move allows the user to jump from wall to wall in narrow spaces.
This move is similar to the Wall Jump maneuver, except that the user can only move vertically across the walls. When approaching two walls that are close to each other, the user must perform a Homing Attack into the wall to grab onto it. The user can then jump directly vertically from one wall to another. Depending on the user's skills, the user can either continuously hang onto the wall or even move around on it.
This move is primarily used to cross large gaps or bottomless pit. By performing the Triangle Jump on the walls near them, while moving forward, the user can cross such obstacles.
The Triangle Jump first appeared in Sonic Heroes as a maneuver that could only be performed by Team Sonic's, Team Dark's and Team Chaotix's speed character, namely Sonic the Hedgehog, Shadow the Hedgehog and Espio the Chameleon. When Sonic and Shadow uses the Triangle Jump, they can only hang onto the wall for a short time before falling off, while Espio can hang onto the wall on for an unlimited amount of time.
Shadow the Hedgehog
The Triangle Jump appeared in the following game Shadow the Hedgehog and was only used by Shadow the Hedgehog. Here, Shadow demonstrated the ability to move around on the wall he used Triangle Jump on, for a short period of time.
